TO ALL WHOM IT MAY CONCERN:

Be it known that I, WILLIAM WESTLAKE, of the city of Brooklyn, in the State of New York, have invented a. certain new and useful Improvement on Lanterns; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings and the letters and marks thereon.

An important and leading feature of my invention relates to a provision whereby theordinary conductors" lantern may be easily and conveniently converted into or used as a signal lantern. This may be effected by staining, painting, or otherwise coloring a certain portion of theglobo or glass of the lantern, so that a certain portion will be transparent or colorless while another portion will be red, green, or blue, or of some other color. The drawings, forming part of this specification, show this provision embraced in the lantern illustrated by having connected therewith a detachable part of a prominent color.

Figure 1 of these drawings is a view by vertical section of a lantern constructed under my improvement; while Figure 2 is a view, by vertical section, of a part of the glass and a part of the cap or dome of the lantern.

In both of these figures where like parts are shown like marks and letters are used to indicate the parts.

It will be noticed that around the globe or glass of the lantern there is a section of a glass or globe of red color, which section can readily be detached, so that while it is on or over the globe the lantern may be used for the usual purposes, as alsofor a signal lantern; and while it is oil the lantern will be like the usual conducto'rs lantern. This section, a, over the globe, b, may be red or of any desired color, and of such shape, and upon or around such part of the globe as may be preferred. In order to accommodate the dome or the upper part of the lantern, marked a, to the difference of lengths of globes I place, suitably attached, within this parts a series of screw-threads, within which or into which fit the threads of the screw (1, which threads are here shown attached to a plate, e, the cut and upturned parts f of which form the thumb and finger-pieces for turning the screw. The moving upwards or downwards of this screw will be easily accomplished, and thus the accommodation be had for fitting in the globe. In ordinary lanterns the lamp or oil pot will lose oil under the motions of carrying it around, and, of course, the oil thus escaping will soil whatever it comes in contact with. The lamp or oil pot of this lantern is so constructed as to prevent the escape and loss of oil. Above the usual top-plate g of the lamp is fitted a cap, it, having a hole large enough for the entrance or exit of the tubes and their plate, so that whatever oil may escape above the plate 9 of the lamp will be surrounded by the cap it, and, through the holes i of the plate g, find its way back into the lamp or oil pot. The springs j, for holding the lamp or oil pot in place, it will be noticed, have a turned-down lip or extension, In, which is attached to the sides of the pot, Much greater elasticity. is obtained from this spring than from such as have the end attached to the sides of the pot; and there is less danger of this spring being broken.

What I claim as my invention, and desire to secure by Letters Patent, is-- 1. Converting the conductor s lantern into a signal lantern by the means and substantially as herein recited.

2. I claim accommodating the globe or glass of the lantern by means of the screw-plate connected to the part c, substantially as herein described.

3. I claim the cap it above the plate 9 for preventing the escape of the oil as herein named. This specification signed this fifth day of November, 1866. I
